Global attestation procedure

ABSTRACT

A method, computer program product, and system for authenticating a computing device by geographic attestation includes a processor utilizing executing an authentication application utilizing location services executing on the computing device to obtain location data from the location services. The processor obtains the location data and creates and encodes a data structure in a secured area of a memory; the data structure is only accessible to the authentication application. The processor transmits to an authentication server, an authentication request that includes the encoded location data, requesting access to secure content. The processor obtains a request to query identifiers proximate to the computing device for additional location information and queries the identifiers and transmits this additional location information to the authentication server. The processor receives a notification and based on obtaining the notification, erases the secured area and turns off the location services on the computing device.

BACKGROUND

Geographic attestation, i.e., the confirmation of a location of a user, can be utilized as a boundary for this user to access protected data. For example, the access of users to their medical records is can be enabled or denied based on the location of the user. In some existing systems, users who want to access to their medical account information must be on a hospital premise to do so.

DETAILED DESCRIPTION

The accompanying figures, in which like reference numerals refer to identical or functionally similar elements throughout the separate views and which are incorporated in and form a part of the specification, further illustrate the present invention and, together with the detailed description of the invention, serve to explain the principles of the present invention. As understood by one of skill in the art, the accompanying figures are provided for ease of understanding and illustrate aspects of certain embodiments of the present invention. The invention is not limited to the embodiments depicted in the figures.

As understood by one of skill in the art, program code, as referred to throughout this application, includes both software and hardware. For example, program code in certain embodiments of the present invention includes fixed function hardware, while other embodiments utilized a software-based implementation of the functionality described. Certain embodiments combine both types of program code. One example of program code, also referred to as one or more programs, is depicted in FIG. 4 as program/utility 40, having a set (at least one) of program modules 42, may be stored in memory 28.

Current geographic attestation processes are vulnerable to hacking. In current processes, an application determines the location of the user by locating the individual within a virtual polygon to localize the area of presence of the user. In order to access the desired information, the user provides account credentials through a mobile application, along with other key attributes, to an authentication server. The latitudinal and longitudinal coordinates of this user are ascertained and also passed to the server, for example, in secured markup language. Assisting in ascertaining this location information are physical “identifier” devices that are spatially embedded throughout the premise to support verification processes across one or more of the aforementioned polygons. These systems are vulnerable to hacking because a user's account could be hacked by altering the latitudinal and longitudinal coordinate data, which are data that are essential to the authentication of the user. These data are vulnerable to hacking even if the mobile application encodes the data using a Geohash encoding algorithm to protect the information.

Certain embodiments of the present invention provide advantages over known global attestation procedures. As aforementioned, applications that require certain geographical/location information in order to access secure information are susceptible to malicious accesses of the location information, compromising the security of the data protected by the geographic attestation requirement. Certain embodiments of the present invention prevent accesses to and guard the authenticity of geographic information that is utilized as part of an authentication process, in order to prevent sensitive data from being compromised and therefore serve to optimize global attestation procedures to enable robust security to avoid the possibility of hacking, without modifying the hardware of existing computing environments that perform global attestation. To this end, certain embodiments of the present invention may include improvements to this computing technology.

In order to improve data security computer technology, certain embodiments of the present invention include an improvement that is inextricably tied to computer technology, specifically, one or more programs obtain location data, for example, using a Global Positioning System (GPS) and use this location data to create a data structure within a secured area of a computing devices. This secured area can be referred to as an “invisible memory area” because the area of the memory in which the one or more programs store the location information is only accessible to an authentication application, but not to any other application executing on the computing device.

In an embodiment of the present invention, one or more programs may store geographic/location data in a secured memory area and further protect the integrity and security of the data by generating an encryption key along with the location data.

In addition to storing geographical/location data in a secured memory area and encrypting this data (generating a key at the time of storage), embodiments of the present invention may further secure this data and prevent the data from being obtained by malicious accesses by matching, authorizing and erasing the data when the location information is acquired by an authorized authentication server, In certain embodiments of the present invention, once accesses to secure data by a computing device are authorized by an authentication server, and then one or more programs turn off the GPS services of the computing device to save power and to prevent additional attempts at obtaining the location data.

FIG. 1 is a diagram that illustrates certain aspects of a computing environment 100 into which aspects of some embodiments of the present invention can be implemented and utilized. Denoted in FIG. 1 is a polygon 110 that defines an area and as long as a computing device is located at latitudinal and longitudinal coordinates that fall within the area of the polygon 110, the device is at a geographic location that could be authorized by a geographic attestation process to access the secure content 140 (e.g., medical records) to which an authentication server 120 serves as a gatekeeper. As understood by one of skill in the art, validation through geographic attestation may be only a portion of the authentications required for one or more programs executing on the authentication server 120 to permit an authorized user device 130 a-130 b in the polygon to access the secure content 140. For example, one or more programs executing on the user devices that pass the geographic attestation stage of an authorization may also be required, by the authentication server 120 to supply additional credentials.

To illustrate how the polygon 110 defines an authorized geographic location, FIG. 1 depicts more than one mobile device, a first user device 130 a, a second user device 130 b, and a third user device 130 c. The first user device 130 a and the second user device 130 b are at locations from which the authentication server 120 could permit one or more programs executing on these user devices 130 a-130 b to access the secure content 140. However, the third user device 130 c is at a location from which the authentication server 120 would not permit access to the secure content 140, as the third user device 130 c would fail the geographic attestation process by being outside of the polygon 110. Physical identifiers 115 a-115 c are spatially embedded throughout the premise, and depicted in FIG. 1 in polygon 110, to support verification processes across the polygon 110.

FIG. 1 depicts the authentication server 120 as being inside the polygon 110 and the secure content 140 as being outside of the polygon 110, as merely one example of a possible configuration of a technical environments that utilizes aspects of an embodiment of the present invention. The locations of authentication server 120 and the secure content 140 may vary across various embodiments of the present invention. For example, the authentication server 120 and the secure content 140 may be located on the same physical machine, in an embodiment of the present invention or the secure content 140 may reside on a different physical machine than the authentication server 120 that is accessible to the authentication server 120. Also, although portrayed as a single entity, for ease of understanding, the one or more of authentication server 120 and/or the secure content 140 may be comprised of more than one physical computing node. For example, both authentication and storing of secure content, in an embodiment of the present invention, may be handled by various computing resources over a distributed computing environment, including but not limited to, a cloud computing environment.

As discussed above, in an embodiments of the present invention, the authentication server 120 utilizes the geographic location of a user device 130 a-130 c as at least part of the criteria in determining whether to authorize the device to access the secure content 140. As illustrated in reference to the first user device 130 a, each user device may include a location device or service 132 a (e.g., a GPS module) that when enabled includes program code that communicates with a GPS satellite 150 in order to determine the latitudinal and longitudinal location of the device. Program code executing on a device or on a computing node with access to a device, may enable and disable the location device or service 132 a in a given device.

FIG. 2 depicts a workflow 200 of an embodiment of the present invention. Throughout the explanation of this workflow 200 references are made to elements of FIG. 1 in order to assist in illustrating certain aspects of embodiments of the present invention.

In an embodiment of the present invention, in order for a computing device (e.g., FIG. 1, 130 a) to be authenticated by an authentication server (e.g., FIG. 1, 120) to access secure content (e.g., FIG. 1, 140), program code executed by one or more processors of the computing device that is part of an authentication application utilizes location services (e.g., a GPS module) in the computing device to acquire location data (210). In an embodiment of the present invention, the program code may enable the location services, which communicate with a GPS satellite and utilize the data from the GPS satellite to determine the location of the computing device. The program code obtains the location data from the location services.

Returning to FIG. 2, upon obtaining the location data, the program code creates a data structure in a secured area of a memory of the computing device that is only accessible to the authentication application (220). The program code encodes the location data by applying a desired level of encryption (230). In an embodiment of the present invention, the secured area of the memory can be understood as an “invisible memory area” because it is only visible to the program code associated with the authentication application and cannot be accessed by other applications executing on the computing device. In an embodiment of the present invention, the secured area of the memory in which the program code stores the location information is owned only by the authentication application and the user of the computing device cannot access and therefore, alter, the data acquired via the location services. In an embodiment of the present invention, the secured area is part of Non-Volatile Memory accessible to the application or Flash backed Dynamic Random Access Memory (DRAM). In an embodiment of the present invention, the secured memory area is a Non-Volatile Dual In-line Memory Module (NVDIMM) in the Flash backed DRAM memory and is only accessible to the authentication application because it is locked by the program code erases the data before the release of the memory area. In an embodiment of the present invention, after the program code stores the location information in the secured area, the information only remains in the stored area for a short amount of time, for example, because the program code deletes the information after the computing device is successfully authenticated.

As aforementioned, the program code of the authentication application locked the secured area so that no other application can access the stored location data. In various embodiments of the present invention, the program code may utilize differing methods to lock the secured area. In an embodiment of the present invention, the program code encrypts and stores the location data and sends an encrypted key using MRS commands to DRAM and its content is backed up with Flash memory. In embodiments that utilize this form of locking, only when the key is matching will the memory controller of the device enable the content to be opened by the program code. The memory controller will generate different keys each time the program code stores location data, to ensure that the location data is not hacked. In an embodiment of the present invention, the memory controller can generate various keys based on the timestamps of the times of storage of the location data. In an embodiment of the present invention, the secured area of the memory is locked because the aforementioned Flash memory part is protected by the Operating System (OS). In an embodiment of the present invention, the secured area of the memory comprises a new data structure, which can be understood by the authentication application and access is provided by the memory controller only when the authentication is successful.

In an embodiment of the present invention, the Flash memory address is fixed, so whenever the authentication application is invoked, it will assume that the data was acquired from the GPS, processed, encrypted, and stored in the secured section, and then it will try to authenticate. If it is successful, the OS or the application will be able to access the location data different methods. In an embodiment of the present invention, if an attempt is made by a program to access the secure area without the correct encrypted key, one or more programs executed by the computing device, including but not limited to the firmware of the computing device, will automatically erase the location data.

Returning to FIG. 2, in an embodiment of the present invention, the program code sends an authentication server (e.g., FIG. 1, 120) a request to authenticate the computing device (e.g., FIG. 1, 130 a) for access to secure content; the request includes the encoded location data (240). In an embodiment of the present invention, the program code may also send additional data, including credential information, to the authentication server, together with the encoded location data from the invisible memory.

Upon receipt of the encoded location data, one or more programs executing on a processing resource on or accessible to the server decode the encrypted location data and determine where the computing device is located (250). For example, the program code may determine the polygon in which the computing device is located, according to the location data received by the authentication server.

One the program code has decrypted the location information, it attempts to authentication accuracy of the information. The program code requests that the computing device query identifiers (e.g., FIG. 1, 115 a-c) proximate to the computing device for additional location information (260). One or more programs executing on the computing device query proximately located identifiers and pass the location information obtained in response to these queries to the authentication server (270). If the location data supplied by the computing device to the authentication server is accurate, identifiers proximate to the computing device should supply location credentials that situate the identifiers in the same polygon as the computing devices. One or more programs at the authentication server obtain this additional location information and compare the additional location information to the location information to verify the accuracy of the location information (280).

Based on the location information matching the additional location information (e.g., both the computing device and the identifiers indicating locations with the same polygon) one or more programs at the authentication server send an acknowledgment to the computing device to indicate a successful authentication (290 a). Once the authentication server has authenticated the computing device, the authentication server enables queries originating from the computing device to access the secure content. Based on receiving the authentication, the program code of the authentication application erases the secured area and turns off the location services on the computing device (295).

Based on the location information not matching the additional location information, the one or more programs at the authentication server send an acknowledgment to the computing device to indicate that the authentication is not successful (290 b). Based on receiving this response, the program code of the authentication application erases the secured area and turns off the location services on the computing device (295). In an embodiment of the present invention, the program code may attempt to authenticate the computing device after an unsuccessful authentication by requesting location data from the computing device and/or additional location data from the identifiers via the location device a predefined amount of times before determining that the authentication is unsuccessful and sending the notification to the computing device.

Aspects of certain embodiments of the present invention enhance geographic attestation by introducing heightened security into this type of authentication. For example, in embodiments of the present invention, the workflow depicted as FIG. 2 is accomplished in a manner that is not visible to the user of the computing device (e.g., FIG. 1, 130 a). Additionally, because the secured area of the memory of the computing device, where the program code stores the location data retrieved by the location services of the computing device, is exclusive to the authentication application, the user of the computing device cannot alter the location data because the user cannot access this area of the memory nor could a hacker access this area to make changes to the location data, for example, the latitudinal and longitudinal values. Because the location data is obtained by the application via location services on the computing device that access a GPS satellite, the location services (e.g., GPS module) the location data are robust (and reliable) data points. In addition to being accessible exclusively to the authentication application, in embodiments of the present invention, the secure memory area and the data within is accessible with encrypted keys and if accesses are attempted without the proper credentials, the firmware deletes the contents of the secure area automatically. As seen in the workflow 200 of FIG. 1, aspects of an embodiment of the present invention are atomic and the processes described are atomic and include no hooks that user could utilize to change the described protocol. Embodiments of the present invention can be implemented in existing computing environments because the aspects described do not require additional hardware components and can be accomplished by the firmware of the computing device and the authentication server and/or an application running on the OS of one or more of these computing nodes.

FIG. 3 is a workflow 300 that depicts certain aspects of an embodiment of the present invention from the vantage point of a computing device seeking authentication to access secure content. In an embodiment of the present invention, program code of an authentication application executing on one or more processors of a computing device utilizes location services in the computing device to acquire location data (310). In an embodiment of the present invention, the program code may request a GPS module to communicate with a GPS satellite in order to obtain the latitudinal and longitudinal location of the computing device. Based on obtaining the location data, the program code creates a data structure from the location data in a secured area of a memory of the computing device that is only accessible to the authentication application (320). In an embodiment of the present invention, the program code encodes the location data (330). When encoding the location data, the program code may generate an encryption key that the authentication application can utilize to access the data. In the event that a process attempts to access the data with an incorrect key, in an embodiment of the present invention, the program code deletes the data structure.

Returning to FIG. 3, in an embodiment of the present invention, program code sends an authentication server a request to authenticate the computing device for access to secure content; the request includes the encoded location data (340). Responsive to sending this request, in an embodiment of the present invention, the program code obtains a request from the authentication server to query identifiers proximate to the computing device for additional location information (350). The program code queries proximately located identifiers and passes the location information obtained, in response to these queries, to the authentication server (360). Responsive to the submission of the additional location information, in an embodiment of the present invention, the computing device either obtains a notification from the authentication server and is able to access the secure content after receiving the notification or the computing device receives a notification that it has not been authenticated and is therefore unable to access the secure content (370).

Whether or not the computing device is authorized to access the secure content, responsive to receiving the notification, in an embodiment of the present invention, the program code erases the secured area and turns off the location services on the computing device (380).

In an embodiment of the present invention, an OS can read the secured area (e.g., a Flash private memory) only if authorized and the information required for this authorization to occur is only available to the authentication application, which is executed by the OS. In an embodiment of the present invention, the program code sends the location data DRAM through an MRS command. If it is authenticated, then program code in the DRAM will process the data as the location data is encrypted in this embodiments of the present invention when it is in DRAM. From DRAM, the program code moves the location data to Flash, which is a NVDIMM that can back up the data. Because this information is hard-coded, in this embodiment of the present invention, the memory controller or the computing device knows in which block address to store this location data and it will create a new secured data structure for the authentication application to access. When the authentication application or the OS needs to access this data, it needs to authenticate first with DRAM if it's successful, then program code in DRAM moves control to a secondary memory wherein the location data can be read, for example, based on a partial restore function in NVDIMM, and takes the location data and puts this data into DRAM for the application to utilize. Once a process is complete, for example, an authentication has succeeded or failed, the program code of the memory controller erases the secured memory and the same area can be used for different purpose. In another embodiment of the present invention, although the contents of the memory are erased, the memory controller may preserve the memory location for future uses by the authentication application, depending on the memory availability.

In an embodiment of the present invention Abstraction Layer Application Programming Interfaces (APIs) are utilized by the program code to read hardware registers in the computing device and access memory content directly from OS. In this embodiment of the present invention, program code is able to read the secured content of the Flash memory after authentication in DRAM. Specifically, after authentication in DRAM, the hardware automatically restores the content of Flash memory into DRAM and then the memory controller takes the location data from predetermined address of DRAM (e.g., unused MRS register and through MPR read) and pushes the data into a hardware register which can be read by the OS.

An embodiment of the present invention includes a computer-implemented method where program code of an authentication application executed by one or more processors of a computing devices, utilizes location services on a computing device to obtain location data from the location services, Based on obtaining the location data, the program code creates and encodes a data structure from the location data in a secured area of a memory of the computing device, wherein the data structure is only accessible to the authentication application. The program code transmits, to an authentication server, an authentication request, where the authentication request includes the encoded location data, and the authentication request is a request for access to secure content via the authentication server. The program code obtains, from the authentication server, a request to query identifiers proximate to the computing device for additional location information. Responsive to the request, the program code queries the identifiers for the additional location information and transmits the additional location information to the authentication server. The program code obtains a notification, responsive to the authentication request, from the authentication server and based on obtaining the notification, the program code erases the secured area and turns off the location services on the computing device.

In an embodiment of the present invention, prior to utilizing the location services, the program code initiates the location services on the computing device.

In an embodiment of the present invention, the authentication server decodes the encoded location information and compares the location information to the additional location information to determine if the location information and the additional location information indicate locations in a similar geographic area.

In an embodiment of the present invention, the location information includes a latitudinal coordinate and a longitudinal coordinate, describing a position of the computing device. In an embodiment of the present invention, the various location information is in a similar geographic area when the latitudinal coordinate and the longitudinal coordinate describing the position of the computing device indicate a location in a virtual polygon defining a geographic area and the additional location information comprises latitudinal coordinates and longitudinal coordinates indicating additional locations in the virtual polygon.

In an embodiment of the present invention, the notification is either an authorization to access the secured content or a denial of access to the secured content. In an embodiment of the present invention, when the notification comprises the authorization to access the secured content, the program code accesses a portion of the secured content via the authentication server.

In an embodiment of the present invention, the encoding includes generating an encryption key, wherein the authentication application utilizes the encryption key to access the data. In this embodiment, prior to obtaining the notification, the program code may obtain an access request to access the data structure in the secured area of the memory, where the access request does not comprise the encryption key. In this situation, the program code may delete the data structure.

In an embodiment of the present invention, the secured area of the memory is either a portion of Non-Volatile Memory or Flash backed Dynamic Random Access Memory.

It is understood in advance that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.

Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.

Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.

Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported providing transparency for both the provider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based email). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for loadbalancing between clouds).

A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure comprising a network of interconnected nodes.

Referring now to FIG. 4, a schematic of an example of a cloud computing node is shown. Cloud computing node 10 is only one example of a suitable cloud computing node and is not intended to suggest any limitation as to the scope of use or functionality of embodiments of the invention described herein. Regardless, cloud computing node 10 is capable of being implemented and/or performing any of the functionality set forth hereinabove. In an embodiment of the present invention, both the user computing devices 130 a-130 c (FIG. 1) and the authentication server 120 (FIG. 1), can be understood as cloud computing node 10 (FIG. 6) and if not a cloud computing node 10, then a general computing node that includes aspects of the cloud computing node 10.

In cloud computing node 10 there is a computer system/server 12, which is operational with numerous other general purpose or special purpose computing system environments or configurations.
